DESCRIPTION OF NATIONAL GENETIC EVALUATION SYSTEMS

Country (or countries)	DFS	
Main trait group1
NOTE! Only one trait group per form!	Workability traits
	
Breed(s)	Holstein	
Trait definition(s) and unit(s) of measurement2
Attach an appendix if needed	1) Milking speed (1-9)
2)Temperament (1-9)	
Method of measuring and collecting data	1) Daughters classified are from daughter group classification and flow data from milk recording. If flow is available classification is discarded
2) Daughters classified are either from daughter group classification or herd classification system	
Time period for data inclusion	1) Cows classified since 1988 and flow data since 2008
2) Cows classified since 1988	
Age groups (e.g. parities) included	Parity 1	
Other criteria (data edits) for inclusion of records	1) Flow data from 30 – 240 DIM	
Criteria for extension of records (if applicable)		
Sire categories	AI-sires	
Environmental effects3, pre-adjustments 	1) Adjustment for heterogeneous variance within country x year. Adjustment to same genetic variance for flow and classifications
2) Adjustment for heterogeneous variance within country x classifier x year	
Method (model) of genetic evaluation3	ST AM BLUP
1) Flow observations are weighted to account for differences in h2.
Weights:
1 flow obs.:             1.86
Avg. 2 flow obs.:    2.30
Avg. 2 flow obs.:    2.49
Avg. 4-7 flow obs.: 2.68	
Environmental effects3 in the genetic evaluation model	1)Classification Calving month, age or age x lactation, lactation stage, classifier x time period, herd x time period as a fixed effect, breed x year, month of classification, time at visit, calving year, herd x time period as a random effect
Flow:
Calving month x year, age, no of flow obs. in average, herd x time period as a fixed effect

2) Herd*time period (5years of classification), country*year*month, country*lactation stage, country*time of visit, classifier*year. Random effect: herd*year	
Adjustment for heterogeneous variance in evaluation model	No	
Use of genetic groups and relationships	Yes	
Blending of foreign/Interbull information in evaluation	No	
Genetic parameters in the evaluation	Use Appendix GE for heritability/genetic variance estimates; for multiple-trait genetic evaluations, provide genetic correlation estimates between traits separately.
Use also appendices PR, CO, BCO, SM, LO, CA, as applicable, if you participate in the international genetic evaluations of Interbull	
System validation	INTERBULL method III	
Expression of genetic evaluations
If standardised (e.g. RBV), give standardisation formula in the appendix	(EBV-Mean)*10/Std)+100
	
Definition of genetic reference base
Next base change	Mean: Cows which is 3-5 years of age.
Std: Sires born 1997 and 1998 with minimum 15 classified daughters.
November 2014	
Calculation of reliability	Interbull procedure	
Criteria for official publication of evaluations	15 classified daughters	
Number of evaluations / publications per year	4	
Use in total merit index4		
Anticipated changes in the near future

1) Either: Production (e.g. milk, fat, protein), Conformation, Health (e.g. mastitis resistance, milk somatic cell, resistance to diseases other than mastitis), Longevity, Calving (e.g. stillbirth, calving ease), Female fertility (e.g. non-return rate, interval between reproductive events, number of AI’s, heat strength), Workability (e.g. milking speed, temperament), Beef production, Efficiency (e.g. body weight, energy balance, body conditioning score), or Other traits.
2) Indicate frequencies per category if the trait is categorical and specify transformation of data if practiced.
3) Use abbreviations for most common effects (see document with list of abbreviations at http://www-interbull.slu.se/service_documentation/General/list_of_abbreviations.rtf) and indicate random (R) or fixed (F).
4) Please give economic weights and indicate how they are expressed (preferably in genetic standard deviation units).
